My invention relates to pneumatic feed mechanisms for feeding papers or paper sections or like articles from one end of a stack or pile.

The objects of the invention are to provide an improved construction of pneumatic feed mechanism of the class specified; to'secure rapidity and efliciency in operation; to secure simplicity of structure; and to provide a 3? mechanism particularly well adapted to feed parts or sections of a newspaper.

' In the accompanying drawings Fig. 1 is a front elevation of a pneumatic feed mechanism embodying my invention;

Fig. 2 is a plan view of the same;

Fig.3 is an end view looking toward the left hand end of Fig. 1; 7

Figs. 4, '5 and 6 are cross sections taken on lines 4.-' l,' -5 and 66, respectively, in

" Fig. 1;

Figs. 7 8 and 9- are views of details of construction, Fig.7 being taken on line 7 7 in Fig. 9. v f

Referring to the drawings, the feed mechanism shown comprises means such as the uprights 1, 2 and 3 for holding a stack or plle of articles to be fed, such as newspaper sections AA. A supporting member 4: is shown for supporting papers or other'articles, but this support does-not extend entirely underneath the bottom paper, but only for the right hand portion of Ithesame, as shown in F ig's. 4 and5, leaving space underneath the left hand portions of said paper,

" through which the folded edges of the papers or paper sections may pass.

These folded edges of the papers are sup portedand released by. two sets of support-' ing fingers 5-5 and 66. The fingers 55 have hooked or bent ends 7 adapted to slide underneath the papers A and said fingers are mounted on blocks 8 carried by a rock shaft 9 which has a crank arm 10 pivotally connected with a link 11 which latter is carried by a forked sliding member 12 actuated by a cam 13' on a rotary shaft 14, so that the rotation of shaft 14 causes cam 13 to act against roller 15 and so cause link 11 to swing 3 rock shaft 10 and rock shaft 9 so asto swing fingers 5 back and forth underneath the folded edges of papersections A.

The other fingers 6 are carried by blocks 17 on the rotary shaft 18 andshaft 18 is rocked by a crank arm 19 connected with a sliding member 20' having a forked end 21 straddling rotary shaft 22 carrying cam 23,

said member 20 also having a roller 24 actuated by-cam23, so that member 20 will'be reciprocated by rotation of shaft 22 and will cause swinging movement of fingers 6.

The operating mechanisms for these two sets of the swingingfingers '55' and 66 are arranged so that the pile will be normally supported by fingers 77 as shown in Fig. 5, but these fingers will be swung away to release the lowermost paper section, and as soon] as this section is released the fingers 66 will be swung up to engage the edge of the next lowermost-paper, and then the fingers 5+5 will be swungback to make full engagement with said second'paper' Which becomes the lowermost paper and so supports the same and the pile.

Pneumatic feed devices or suckers 26-26 are mounted on a rotary tubular member or pipe 27 located below the stack or pile of papers A between the ends offingers 7 and the end support 4. These suckers 26 are adapted toengage the lowermost paper section A when it is released by fingers 7 and pull the same down as shown in Fig.5. Pipe 27 is carriedby bearing 28 mounted on a sliding carriage 29, said carriage 29 being mounted to slide on guideways 30. Carriage 29 is reciprocated byswinging member 31 mounted on a rock shaft 32 and having a forked end which embraces a'nut33. Shaft cause rotation of pipe 27 as the carriage is reciprocated and thus suckers 26 will swing downwardly and be moved bodily backwardly so as to effect such downward swinging and backward movement on the part of the bottom-paper section acted on by the suckers 26, asshown in Fig.5. 7

Pneumatic pressure to the suckers 26 is controlled by a Valve device 44 (Figs. 3, 7,

Thisconsists of a flat block 45 to which is extended a pipe 46 leading from the end of pipe 27 carrying the sucker devices 26. Another pipe 47 leads from block 45 to a pressure reducing apparatus by'which an. exhaust condition is produced for the :suckers- 26.- The block 45 is provided with two channels 48 and 49,- which nearly meet each-other but do. not quite meet, their ends being separated by a' solid portion 50 (Fig. 7 A rotary plate 51 is'mounted in front of the block 45 and provided with a recess 52 adaptedtoalford communication between the-end portions of the channels 48'and49. .The plate 51 is mounted for rotary movement and is rockedby a linkarm 53 connected at 54 with arocker arm; 55, pivoially mounted at its lowe'rend56. Rocker arm 55is actuated by a cam 57 on camshaft 14, said cam 57 cooperatingwithga roller- 58 carried by arm 55' Thus cam-57 will cause'arm 55 to actuate link 53 and the latter in turn will actuate rotary plate 51 and so establish and disest'ablishexhaust connection between exhaust pipe 47 and sucker supply pipe 46 which latter contains a slidable pipe 60 jrunningto tubular member 61 containing one end of sucker carryingpipe27, it beingthus seen that sucker pipe 27: carrying suckers 26'may thus be moved transversely bythe movement of carriage 29 andalso may be turned in tubular member 61 and-bearings 6262, so-as to per mit downward and backward movement of the paper section by thesucker-s, and during such bodily backward and forward movetion to engage bottom paper section A, as

shown inFig. 4', and such suction or exhaust isscutolf from suckers 26 after the bottom paper sectionis drawn down, butbefore it reaches the position} shown in Fig, '5;

' After paper section A is drawnrdown it is engaged by a rotary segment 65'mounted on rotary, shaft' 66,lthef-ront face 67 of said segment 65stri-king' the depressed edge of bottomgp'aper section andswinging the same downwardly sothat it will: movev toward roll 68 and will pass said roll 68 and cylindric surface of segment 67 and so be fed downsection may. be fedin between said roll 70 and segment 65 be further advanced by the same. A pair of exit rolls 71 and 72 are located somewhat below and to one side of segment 65'so as to receive the paperfrom' roll 70 and feed it out to any desired place, either to some other mechanism in the machine or from the machine itself.

Shaft 66 carrying segment 65 also carries gear 73 meshing with pinion 74 on shaft 68a carrying roll 68 and said gear 73 also meshes with gear 75 carried by shaft 70a carrying roll 70, whereby segment shaft 66 drives rolls 68 and 70. Roll shafts 71a and 7 2a carrying rolls 71 and 72 respectively, are provided with pinions 76 and- 77, the former of which meshes with gear 73 on segment shaft 66 and the latter of which meshes with pinion 76, whereby segment shaft 66 drives rolls 71 and 72 also.

Roll 68 is preferably mounted for elastic or yielding. adjustment to permit paper sections of different thickness to'pass between it and segment 65, such adjustment consisting in mounting shaft 68a .in a slideway 80 subject to pressure of a spring 81 tending to force roll 68 toward segment 65 but yielding asrequired by thickness of paper section. B01170 is also yieldingly mounted as by mounting shaft 7 0a in a slidable bearing 82 controlled by a spring 83carried by swinging frame 84 pivoted at 85 and having an arm 86 controlled by a spring 87 so that shaft 7 0a and with it roll 70 may have ample adjustment for accommodating various thicknesses of paper. Also roll'71is adjustable with ref erence to roll 72, as by mounting roll shaft 71a in a slidable bearing controlled by spring 89 permitting sliding up and down movement of roll 71.

For guiding paper from roll 68 to roll 70,

and from roll 70 toexit rolls 71 and 72, a

swinging guide member 90 is provided having guide flanges or members 91 and 92, the former to guide papers from roll 68 to roll 70 and the latter to guide them from roll 70 to exit rolls 71 and 72. This member 90 is pivotally mounted on rock shaft 85, which latter is provided with a handle 94, Fig. 1, by which member 90 may be swung down to get it out of the way in case papers become jammed between segment 65 and rolls 68 and 70, and then fed outwardly to another part of'the'm'achinmor to a set stack or pile of exit'rolls 71 and 72. p
